High Score! Enter your name below to get on the scoreboard:
Your goal is to make a cool planetary system that lasts at least
400 ticks (about 10 seconds) without the planets crashing into each
other or the walls.
Click and drag to add planets or to change existing planets'
positions or velocities.
Use either the scroll wheel or the A
and Z keys on the keyboard to change planets' masses.
Shift + click
to remove planets.
When you're ready to try out your setup, click the "go"
button. If your system makes it for 400 ticks, you will
receive a score based (in theory) on how "cool" the orbits
are. Good luck getting on the high scores! [Edit June 2019: No more high scores, sorry]
